Hunt Bike Wheels got back to me.
"Thank you very much for your email. The competition isn’t designed to be an exclusively male competition, although reading back the email I will accept that it could seem that way.
Just to clarify if the Catford record is beaten then that person will win the prize, if a man beats the men’s record they would win and equally if a woman beats the woman’s record they also win."
Big thumbs up for Hunt. I hope that they clarify publicly.
I wish I was good at hill climbing but, alas, I'm shit at it.
